For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

A starting signal for cell division: Molecular switch ensures that cells divide at the right time
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
The awe-inspiring process of cell division can turn a fertilized egg into a baby – or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...
A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail the ...
High-resolution imaging shows how MraZ breaks and deforms to attach to repeated DNA sequences, activating the gene cluster ...

How egg cells control the timing of cell division
A protein known as MPS1 helps to ensure that a key process during cell division of oocytes—unfertilized egg cells—occurs in a timely manner, RIKEN biologists have discovered. This finding in mice may ...
When we talk about memories in biology, we tend to focus on the brain and the storage of information in neurons. But there are lots of other memories that persist within our cells. Cells remember ...
The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...
